Norwid Behrnd c9ef4864c0 Cherry-pick tester-time (0291b2d), d2n time stamps
Checks of appendfilename --smart-prepend now consider date2name'
default time stamp (YYYY-MM-DD), the by date2name --withtime
(YYYY-MM-DDTHH.MM.SS), or absence of such by pattern recognition
with regular expressions.

"""Test pad for functions by appendfilename with pytest.
Written for Python 3.9.9 and pytest 6.2.4 for Python 3 as provided by
Linux Debian 12/bookworm, branch testing, this is a programmatic check
of functions offered by appendfilename. Deposit this script in the root of
the folder fetched and unzipped from PyPi or GitHub. If your system
includes both legacy Python 2 and Python 3, pytest for Python 3 likely
is named pytest-3; otherwise only pytest. Thus, adjust your input on
the CLI accordingly when running either one of
pytest -v test_appendfilename.py
pytest-3 -v test_appendfilename.py
These instruction initiate a verbose testing (flag -v) reported back to the
CLI.re will be a verbose report to the CLI The script either stops when one of
the tests fail (flag -x), or after completion of the test sequence. In both
cases, the progress of the ongoing tests is reported to the CLI (flag -v)."""
